Definitions

  • the invention relates to a connector assembly for interconnecting optical and/or electrical conductors of the type described in EP-A-0 571 037, prior art in the sense of Article 54(3) EPC.
  • means are provided for exerting forces for pressing the cooperating reference surfaces and the guiding plates towards each other during coupling the connector parts. These means include three separate spring means.
  • the invention aims to simplify the construction of this connector assembly.
  • the connector assembly shows the features of claim 1.
  • Fig. 1 is a cross section of an embodiment of the connector assembly of the invention wherein the connector parts are shown in the disconnected position.
  • Fig. 2 is a cross section according to the plane II-II of the right connector part of Fig. 1.
  • Fig. 3 is a schematical top view of the left connector part of Fig. 1.
  • Fig. 4 is an end view of the right connector part of Fig. 1.
  • a connector assembly for interconnecting optical and/or electrical conductors, in particular the contact pads thereof, in an embodiment for providing connections between printed circuit boards, for example a first printed circuit board 1 and a second printed circuit board 2.
  • optical fibres are embedded in the printed circuit boards 1 and 2, said optical fibres in the printed circuit board 1 being provided with contact pads in one plane with the surface of the printed circuit board 1.
  • a first guiding plate 3 is embedded in the printed circuit board 1, a main surface of which can lie in one plane with the surface of the printed circuit board 1.
  • the main surface of the guiding plate 3 lies below the surface of the printed circuit board 1.
  • Guiding channels 4 are provided in the guiding plate 3, wherein an optical fibre is located in each of said guiding channels 4 so that the position of the optical fibres is determined by the guiding channels 4. These guiding channels 4 incline gradually upwardly to the main surface of the guiding plate 3 so that the ends of the optical fibres are guided towards this main surface. The portions of the optical fibres projecting out of the printed circuit board 1, are polished in such a manner that they will be lying in the surface of the printed circuit board 1.
  • the guiding plate 3 together with a housing 5 at least partially enclosing this guiding plate 3 forms a first connector part 6 of the connector assembly.
  • a second connector part 7 comprises a housing 8 which can be received in a receiving space 9 of the housing 5.
  • a moveable element 10 is mounted in the housing 8, the end part of which projecting out of the housing 8 is functioning as second guiding plate 11.
  • Guiding channels 12 corresponding with the guiding channels 4 are provided in this guiding plate 11 and these guiding channels 12 also debouch gradually into the main surface of the guiding plate.
  • the optical fibres embedded in the printed circuit board 2 are guided out of the printed circuit board in a manner not further shown and are fixed in the guiding channels 12, so that the position of the optical fibres of the printed circuit board 2 is also determined by the guiding channels 12.
  • the portions of the optical fibres projecting out of the guiding plate 11 are polished in such a manner that contact pads in the main surface of the guiding plate 11 are obtained.
  • the guiding plate 3 comprises a lug 13 with a straight reference surface 14, lying at a predetermined location fixed with very high accuracy with respect to the guiding channels 4. Manufacturing such a straight reference surface at an accurately determined location with respect to the guiding channels 4 is relatively simple from a manufacturing point of view.
  • the lug 13 is provided with aligning edges 15 at its protruding end.
  • the guiding plate 11 is provided with a slot 16 with a straight reference surface 17 lying at the same predetermined location fixed also with high accuracy with respect to the guiding channels 12.
  • the housings 5, 8 are positioned with respect to each other first, whereby a rough positioning is obtained.
  • the element 10 is mounted in the housing 8 moveable in three mutual perpendicular directions, which directions are indicated in the drawing as x-, y- and z-directions.
  • the reference surfaces 14, 17 are parallel to the y-direction.
  • the element 10 comprises a surface 18 enclosing an angle with the x-, y- and z-directions.
  • a pin 19 is slidably mounted in the housing 8, wherein a smooth rounded end of the pin 19 engages the oblique surface 18.
  • the pin 19 has a head 20 engaged by a spring 21 pressing the pin 19 against the surface 18.
  • the single spring 21 exerts a force on the oblique surface 18 which force is distributed in the x-, y-and z-directions.
  • the oblique surface 18 encloses an angle of 45° with each of these directions.
  • the oblique surface 18 itself is preferably smoothly polished so that the friction forces between the end of the pin 19 and this surface are minimal.
  • Positioning in the longitudinal direction of the guiding channels 4, 12 is obtained in a corresponding manner by means of a lug 22 with a straight reference surface 23 extending in the x-direction.
  • This lug 22 is also provided with aligning edges 15.
  • the guiding plate 11 has a slot 24 with a straight reference surface 25.
  • the spring 21 generates a force through the pin 19 and the surface 18 pressing the reference surface 25 of the slot 24 against the reference surface 23 of the lug 22.
  • the spring 21 through the pin 19 and the surface 18 also provides for pressing the contact pads of the conductors against each other in the coupled position of the connector parts 6, 7 by pressing the guiding plate 11 in the direction of the guiding plate 3.
